Mexico: Will Los Zetas Unravel Without Their Leader?

Summary

The arrest of Los Zetas leader Miguel "Z-40" Trevino Morales marks the most significant capture involving a Mexican organized crime leader since 2008. On July 15, Stratfor sources confirmed Mexican and U.S. media reports saying that Trevino was arrested in Nuevo Laredo, Tamaulipas state, and that he was being transferred to Mexico City. Reports indicate that he was arrested late July 14, though that has not been confirmed. At least one source claims Trevino's nephew was also arrested.

This ability stems from the founding members, several of whom deserted from the highly trained Special Forces Airmobile Group unit of the Mexican army. Because ex-military personnel formed Los Zetas, members tend to move up in the group's hierarchy through merit rather than through familial connections. This contrasts starkly with the culture of other cartels, including the Sinaloa Federation. However, Trevino did not originate from the Mexican military like his predecessor, so it is possible that the group's culture may have changed somewhat.

It is unclear who will now try to keep the group together. Trevino's brother, Omar "Z-42" Trevino, will likely continue to maintain his role in criminal operations but it remains to be seen whether he has the capability or respect within the organization to replace his brother.

The places where cartel-related violence could rise as a result of Trevino's capture will depend on the ability of Los Zetas to replace their top leader as well as the strategies of Los Zetas' rivals. Should Trevino's arrest spark an internal struggle for succession, violence could rise in the states in which Los Zetas hold a substantial presence, including Tamaulipas, Nuevo Leon, Zacatecas, San Luis Potosi, Coahuila, Veracruz, Hidalgo, and Tabasco states.
